- SAFETY rm 1 2 Application filed April 11,

' releasement of the point of the pin from the sheath or cap, suchsafety pin including two spring-connected legs, a sheetmetal shield onthe free end of one leg for engagement by the pin formed by the otherleg, the opposite cheeks of the shield having transverse incisions andalso transverse spring catches struck up from the cheeks and defined bythe incisions, and the catches having free ends provided with inward,mutually presented, shoulders past which the pin is adapted to besnapped and held thereby when the safety pin is to be closed.

These being among the objects of the present invention, the sameconsists of certain features of construction and combinations of partsherein described and claimed, and

shown in the accompanying drawings in a preferred and modified form andin which:

Figure 1 is an enlarged side elevation of the improved safety pin in itspreferred form;

Fig. 2 is an enlarged cross-section thereof on the line 22, Fig. 1;

Fig. 3 is a side elevation of a modified form, and

Fig. 4 is an enlarged cross-section on the line 454, Fig. 3.

Similar parts in both of the illustrated, preferred and modified formsof the invention bear the same reference numerals, different numeralsbeing used to point out the specific difference between the. two formsillustrated.

In the drawings, the general type of safety pin is illustrated, the samehaving a leg 5 forming a back bar and a leg 6 which is formed into thepointed pin of the device, and

the two legs are formed in one with a helical spring 7 which connectsthem. Secured in any usual or preferred manner to the back bar or leg 5is the sheet metal shield or cap 8 which may be of any preferredconstructongues;

tion, the same being adapted tov receive and engage with the pointed'endof the pin 6.

The shield or cap 8 is made of suitable metal of a more or less springycharacter which can be bent up by dies. Usually the shield ,01' cap 8 isprovided with opposite checks 9, 10 which provide a pocket between them,in which the pointed end of the pin is received, and as such thesecheeks are fairly stiff and as such'pres-ent little if any resilience. r

In the preferred form of the invention shown in Figs. 1 and 2, thecheeks 9, 10 are provided with integral struck-up tongues 11, one foreachcheek, and the free end of each tongue is bent inwardly so as toform more or less of a shoulder 12. These shoulders 12are presentedmutually towards each other so as tooppose each other and to provide acontracted throat between them. Inasmuch as the shields 9, 10 arecomposed of and formed as'shownin Fig. 2, openings are formed in' both'cheeks, representing the amount'of metal which was removed in order toenable the formation of the spring It will be seen that when .the

the shield or cap 8, said end is pressed with a little force through thethroat formed between the two shoulders 12, thereby pressing 'the spring"tongues 11 outwardly, and then when the pointed end of the pin isseated as shownin Figj2, the free ends'of the ton 1 ac c into suchposition as to retain the pointed end of the pin to its seat.

' In the form of the invention shown in Figs. 1 and 2, the springtongues 11 emerge suitable sheet metal and as the tongues. 11

from the outermost portions of the cheeks 9 and 10, and the free ends ofthe tongues are directed towards'the pin 6 when it is seated in theshield. In the modification of the invention illustrated in Figs. 3 and4 the spring tongues 15 emerge from points at opposite sides of the seatfor 5 the pin, and t e free ends of the tongues extend in a directiontowards the back bar 5, or in an opposite direction to that shown in thereferred form of the invention. In the mo ificd form, the spring tongues15 are also formed at their free ends with inwardly presented or bentportions 16 which form a contracted throat for the entrance of the pinas in the preferred form of the invention. In other words, in thepreferred form, the pin 6 passes the full length of the spring tongues11 in bein seated in locked position, whereas in the m ified form thepin becomes seated and locked between the base portions of the springtongues 15, after the pin has passed 20 by the shoulders 16.

It will be obvious to those skilled in the art that changes maybe madefrom the exact construction shown and described, such as slashing orincising the shield or cap in dif- 2 ferent ways to rovide spring jaws,fingers or tongues, an that such changes can be made without departingfrom the invention as defined in the scope of the appended claims.

What I claim as new is:

1. A safety pin, including two spring-connected legs, a sheet metalshield on the free end of one leg for engagement by the pin formed bythe other leg, the opposite cheeks of the shield having transverseincisions and also transverse spring catches struck up from the cheeksand defined by the incisions, the catches having free ends provided withinward, mutually resented, shoulders past which the in is a apted to besnapped and held there y when the safety pin 1s to be closed.

2. A safety pin, including two spring-connested legs, a sheet metalshield on the free end of one leg for engagement by the pin formed bythe other leg, the opposite cheeks of the shield each having a pair oftransverse incisions and also transverse spring catches struck up fromthe cheeks and each located between and defined by the incisions of agiven pair, the catches having free ends provided with inward, mutuallypresented, shoulders past which the pin is adapted to be snapped andheld thereby when the safety pin is to be closed.

3. A safety pin, including two spring-connected legs, asheet metalshield on the free end of one leg for engagement by the pin formed bythe other leg, and spring catch tongues struck up from the checks of theshield and bent inwardly at their free ends to provide shoulders forminga contracted throat through which the pin is adapted to be pressed so asto be held by the shoulders when the safety Ipin is to be closed.
